The blood from the upper limb is returned to the heart by two sets of veins, superficial and deep. Both sets have valves, and both drain ultimately into the axillary vein. Superficial Veins (fig. 7-1).The superficial veins are highly variable, lie mostly in the subcutaneous tissue, and return almost all of the blood.Digital veins drain into a dorsal venous network in the hand, which leads to two prominent veins, the cephalic and the basilic.oth sets have valves, and both drain ultimately into the axillary vein. Superficial Veins (fig. 7-1). The superficial veins are highly variable, lie mostly in the subcutaneous tissue, and return almost all of the blood.
Radial artery. The radial artery is a major artery in the human forearm. It is close to the surface of the underside of the forearm; when the palm of the hand is pointing upwards, so is the radial artery. The radial artery supplies the arm and hand with oxygenated blood from the lungs. Due to the size of the radial artery, and its proximity to the surface of the arm, this is the most common artery used to measure a patient's pulse. The pulse is checked at the wrist, where the radial artery is closest to the surface. The radial artery is also commonly used when drawing arterial blood for âArterial Blood Gasâ (ABG) measurement. This is done for three reasons: firstly, it is not the only supplier of blood to the arm.
